[Unstable detrusor: usefulness of biofeedback]

Area of Science:

• Urology
• Pelvic Floor Rehabilitation
• Neurology

Background:

• Vesical instability and incontinence frequently co-occur.
• Enuresis and female stress urinary incontinence are common conditions.
• Biofeedback offers a potential non-invasive treatment approach.

Purpose of the Study:

• To evaluate the efficacy of Biofeedback therapy.
• To assess outcomes in patients with enuresis and female stress urinary incontinence.
• To explore the pathogeny and mechanism of Biofeedback in these conditions.

Main Methods:

• Treatment using Biofeedback was applied to 65 cases of enuresis and 39 cases of female urinary stress incontinence.
• The method involved instrumentation easily adaptable to standard electromyographic devices with real-time output.
• Authors discuss the underlying pathogeny and the mechanism of action of Biofeedback.

Main Results:

• Biofeedback achieved disappearance of detrusor instability in 78.2% of enuretic cases and 58.9% of female stress incontinence cases.
• Complete resolution of incontinence was observed in 70.5% of enuretics and 20.5% of female incontinence patients.
• The study highlights differential effectiveness of Biofeedback for instability versus incontinence symptoms.

Conclusions:

• Biofeedback is an effective method for reducing detrusor instability in both enuresis and female stress urinary incontinence.
• While effective for instability, Biofeedback's success in achieving complete incontinence resolution is more pronounced in enuresis compared to female stress urinary incontinence.
• The findings support the authors' hypotheses regarding the pathogeny of these conditions and the mechanism of Biofeedback therapy.
